New Rig Advise/help?

[Dazzed DJ]

Hi all I am looking a building a new system, current one over 4 years old and just want some comments/advise on what I am looking at. The system will be mainly gaiming rig for COD and BF3 when comes out as well as main home computer. While I plan to only run I 1080 monitor on it will look to go three monitors at later date. Ok so to the build

CPU i7 2600k
Motherboard Asus Maximus extreme iV
GPU Nvidia GTX590
Ram 8 Gig of low lat. (1600) 1.5 v prob Ripjaw
PSU Corsair 1200w gold
H70 cooling system (all in one water block)
SSD 120 sytem drive
2 TD harddrive storage
Raven V1 Tower case

I am looking at playing around with overclocking the 2600k thus the reason for the Asus board. I am also playing around with cad design as well as the gaming on this rig. So any comments or advise would be great.

Thanks
DJ
